Talking to Riehl and also reading some of the comments, I came to an agreement that it is true is a bit "overqualified" for a Gunboat.

"But spheres and Cylinders are meant for gas products." Not true. There are spheres and cylindrical shaped storages in the Sci-Fi universe. In Example, the Lucrehulk, Star Wars Trade Federation Battleship.
Anyways, here are the results. It is subject to change.
